+Botspot's collection of 14 Windows screensavers that run well on Raspberry Pi.
+If you don't have Wine installed, this app will install it for you.
+Once installed, you can launch Botspot's Screensavers GUI from:
+Menu -> Preferences -> Windows Screensavers.
+To run in terminal: ~/Screensavers/gui

+In addition to the Windows Screensavers, Botspot's Screensaver GUI also allows convenient installation of GPU-accelerated Xscreensaver, preset to enable the best ones out of 230 screensavers.
